Can story mode characters be used in gta online?

Grand Theft Auto Online operates as a standalone multiplayer component of Grand Theft Auto V, separate from the single-player story mode. While the story mode features three main protagonists—Michael, Franklin, and Trevor—players in GTA Online create their own customizable silent protagonist. The evidence confirms that players control a 'customisable silent pr...' in online mode, indicating no direct transfer or usage of story mode characters. Any appearance of story mode characters in GTA Online is limited to mission-related cameos or passive interactions, not as playable avatars. The online experience is designed around a distinct character creation system, ensuring separation between the single-player narrative and multiplayer gameplay.
